Yes. I’ve been putting that in my Stouts for many years. Adds a lot of body.
Just found this interesting fact about stevia.
Stevia has been reportedly used as an oral contraceptive by women from Paraguayan Matto Grosso Indian tribes (Kinghorn, 2002). This ethnobotanical use has led to significant interest in the effect of stevia extracts on reproductive performance and to a number of investigations exploring the fertility effects of stevia extracts in rodent species.
The most oft-cited study regarding female fertility effects of stevia was conducted by Mazzei-Planas and Kuc (1968).
